Innovative installations take tile from ordinary to sensational. This mirror sits within an asymmetrical opening in the tile, and even the wall sconces are set at different heights. Individual mirrored tiles are interspersed in a random pattern throughout the shower. This is a great idea, but best done by a pro. Using mirrors in wet applications is tricky. Cutting them damages their back coating, allowing moisture to get in and ruin the reflective surface. You would need to use mirrored tiles made in the sizes you need, as well as specific adhesives.
